SPECIFICATION formingpart of Letters Paten'tgNo. 712,132, dated October28, 1902- Appumion nea February 12,1902. serrano'. 93,677. (Nomade.)

To fallu/hom it may concern:

Be it known that I, GEORGE L. HALL, a citizen of the United States ofAmerica, residing in the borough of Brooklyn, city of New York, countyof Kings, and State of New York, have invented certain new and usefulImprovements in Insulated Rail-Jointaof which the following is aspecification, reference being -had therein to the'accompanyingdrawings.

My invention relates to joints between adjacent rails of a railway; andits objects are to provide a strong union for the rail ends and cheapmeans of insulating them from each In some cases it may be found thatthe railjoint described in my application for Letters Patent filedJanuary 18, 1902, Serial No. 90,233, Series of 1900, is not adapted tothe situation and that the joint should be provided with anangle-chair.` y

To these endsv my invention consists of a two-part fish-plate, incombination with an angle-chair, of means of insulating the two parts ofthe fish-plate from each other and of the angle-chair from one of therail ends.

I hereinafter describe a rail-joint embodying the features of myimprovements and then point outthe novel features in the claims, havingreference to the accompanying drawings, in which similar figuresofreference indicate similar parts throughout the'various views, ofwhich- Figure `1 is a plan view, partly in section, of arail-joint'embodyingrnyinvention. Fig. 2 is a side elevation. Fig. 3 isan end View, partly in section, on the line 3 3 of Fig. 1. Fig. 4 is aplan view of a modified form ofthe joint. Fig. 5 is a perspective yviewof the angle-chair. Fig. 6 is a perspective view of a modified form ofthe angle-chair.

1 1 are ends of two railway-rails to be joined.

2 and 3Kare respectively ,parts of a fishplate. Each of said parts 2 and3` is provided with one or more lugs 4 osetting from the same. Theselugs may be so arranged as to be spiked to ties or so as to be run intothe earth, or some of them may be arranged to be spiked to ties andothers to be run into the earth. Said parts 2 and 3 of said fish-plateare also provided with offsetting lugs 5, adapted to be united by one ormore bolts, rivets, or other joining devices 6.

7 and 8 are respectively parts of another fish-plate.. Each of saidparts7 and S is provided with offsetting lugs 9, adaptedjto be ,unitedby one Nrrnn STATESI yPATENT OFFICE. I

or more bolts, rivets, or other joining devices y 10. Of course it willbe understood that lugs 4 may in some cases be omitted from the par-ts 2and 3 of the other fish-plate.

11, 11', and 11l designate the several parts of an anglechair, 11 beingthe part resting y upon the ties and adapted to be spiked theretothrough holes 12, 11 being the upright part and provided with bolt-holes13, and 11 being the supporting part of the chair. Said upright part 11"is formed of a fold or eXtra thicknessof the metal, so that it issubstantially double the thickness of the parts 11 and 11. In this waythe chair, and thereby the joint, is greatly strengthened.

v14 represents pieces ofpacking and insulating material, such as wood,between the upright part 11" of the angle-chair and the correspondingparts 7 and 8 of the two-part fish-plate on that side of the rail ends,said packing material being of sufficient thickness to prevent anyelectrical connection between j' the part 11H of the angle-chair and thelugs 9 of'fthe two-part fish-plate.

15 represents insulating material, preferably7 vegetable fiber, betweenlugs 5 5 of the parts 2 and 3 of one fish-plate and lugs 9 9 of theparts 7 and 8 of the other fish-plate, and extending between the railends 1 1though said insulation may be omitted between the rail ends ifthey are properly separated by airspace.

16 represents bolts passing through the up right part 11" of theangle-chair, the packing 14, the respective parts 7 and 8 of onefishplate, the rail ends 1, and the respective parts 2 and 3 of theother sh-plate.

17 represents thimbles or bushings of insu' IOO It will be readilyunderstood that it is necessary only to insulate from the angle-chairone of the two rail ends, as shownY in Fig. l of the drawings.

22 represents insulating material intermediate of the bottom of the railends and supporting part 1l of the angle-chair. A good method of holdingsaid insulating material in place is shown in Fig. 3. Said insulatingmaterial is provided at each end with a lap 25, adapted to be foldedupon the upper surface of bottom flange of the rail ends, and theanglechair is provided with lugs 23, adapted to pinoli said laps to therail ends, as shown in Fig. 3; but of course I do not limit myself tothismethod of holding said insulating mateterial 22 in place. Theangle-chair may be provided with a corrugated under surface,as shown at24: in Figs. 3 and 4.

In Fig. 4 is shown a modified form of the joint. It is in all respectssimilar to the joint above described, except that the two-part iishplate7 8 is omitted and the packing and insulating material 14 is made of onepiece and extends across the joining-point of the rail ends l l.

What I claim, and desire to secure by Letters Patent, is

1. An insulated rail-joint comprising an angle-chair, a two-partfish-plate on the same side of the rail ends as the upright portion ofthe angle-chair, means of structurally u niting and electricallyinsulating the two parts of said fish-plate; a two-part fish-plate onthe opposite. side of said rail ends, means of struc-- turally unitingand electrically insulating the same; insulating-blocks intermediate theupright portion of the angle-chair and each of the parts of saidfirst-mentioned fish-plate; a plurality of bolts passing through theupright portion of the angle-chair, insulating-blocks, rail ends, andfish-plates;V insulating-bush,- ings between the angle-chair and thoseof said bolts which pass through one of the rail ends, insulatingmaterial between the rail ends and the part of the angle-chair uponwhich they rest, and means of maintaining the rail ends from contactwith each other.
